Where the Assessing Officer levied penalty under section 271(1)(c) on the allegation that assessee had concealed income or furnished inaccurate particulars while claiming exemption under section 10(23C)(vi), but had failed to record proper satisfaction as to which limb of section 271(1)(c) had been violated, the Tribunal was justified in deleting the penalty, and its order did not call for interference.
